Double shock heart treatment trial fizzles out
NCT ID NCT03943693
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial tested whether giving two quick electrical shocks instead of one could better restore a normal heart rhythm in people with atrial fibrillation. It focused on patients with factors that make standard shock treatment less likely to work, such as obesity or lung disease. However, the study was stopped early after enrolling only 5 people, so no meaningful conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
electrical shock (cardioversion)
What this could lead to
If it worked, this could point toward a better way to restore normal heart rhythm in people with atrial fibrillation who are harder to treat.
What could go wrong
This was a very early, tiny trial that was stopped before completion. The results are not reliable, and the approach may not be safer or more effective than standard care.
